The initial printer problems stem from the initial power on.
Just throw the switch and see what happens.
It is called the smoke test and your skill set is in play to the degree of the missing correctness of the device you purchased.

Ah the zen of techno babble.

Holy sparks, batman.

I reflect on my fustration in my 3d printer journey and now can't help helping others.
Unfortunately it is only after they too have become incensed.
Pissed off straight I tell ya!

Well here comes the bad news. And this for anybody reading almost a year later.
Replikeo has gone through a minimization scheme.
They have gotten away from tensioned extruders. They print a single piece and it is either crap or warped.
The exttuder pieces need dremeling to house the motors correctly.
The beds are not spring loaded. You need to buy springs and do this.
The extruder feeds on the new units don't work consistently because of no tension. They grind the filament away leaving dead spots.

That said i have:
Dremeled the extruder brackets to hold the motors correctly.
I have replaced the motor brackets with Bowden tensioning pieces.
I have added springs to the bed and rehomed the z axises.
I have drank two quarts of vodka during this malaise.

But after all this I have gotten two test prints that I can peer into and finally surmise what needs adjustment next.
I am in the process now of releveling the spring loaded bed.

This purchase has gotten me a frame, mounts, motors, and firmware to start analysing the 3d printing world.
It took a life time(40years) of skill sets to get this thing to run. So instead of a $1000 purchase or a build from scratch I have a 2 month process and now am in the running to print objects. I mention this because you will go through a mental turmoil to get things right.

I went to Walmart today and bought the placemat. This comes at an opportune time as I am currently working with the bed issues.

Springs on the bed is a bad idea... most wobble in the X and Y directions. Most have removed them and improved their prints a lot!

They can also compress with heavy large prints on them, causing layer issues

I have no wobble but the compression I did think about. I will cross that bridge when I get there.
Right now I was trying to eliminate all possible problems. I have extruder misfeeds now.

I found there is a stop point and a bit of heavy resistance in the filament feed tube.
So I have to find a supplier or tweek this one.

When checking for temperatures I see this page that states 200C for PLA. 392F is kinda high.
PLA temperature

Another great PLA article

This pointed me to Two errors. My head temperature is too low and with blue tape bed the bed heat should be off.
